what are all of the benefits from GHRPs and CJC?

I know that CJC creates a steady "pulse" of high GH levels, and GHRPs further the release of GH in the body, but could someone please list all of the specific benefits of combining something like CJC 1295 with a GHRP?

But !!!!!! These are what Growth Hormone does, and peptides release gh... so all those will happen BUT AGAIN !! Peptides could have other side effects that we don't know yet, I found something new that peptides have lots of heavy metals in them so I'm researching on that

i guess my two main questions are: how does it compare to a PH in terms of giving muscle gains at an accelerated rate? Do they or don't they?
And, i've read that they increase prolactin and cortisol, but yet how are so many users reporting leaning out and dropping calories even when eating over maintenance?

but how do they compare to PH's in terms of gains? I understand the science behind it, but I'm talking about actual results from the people who've used them. Have you gained muscle and lost fat or not from using GHRP6 and CJC 1295? Or is it just good for tendons, sleep, skin?
